    Chacko, you could perform an SNMP walk against the switch to get an idea of the OIDs and their description. Though I do not think we have one for duplicate IPs.

    Please be aware that you can detect Duplicate IPs based on a test that would inform if two device respond to an ICMP request. Please read the following article for more detail:

    In turn, if you have an SNMP manager / NMS, such as the marvelous NetSight, you then could create an alarm based on the EMS generated in the show log output via syslog.

    At last, what the conclusion is? is there any way a trap to be created whenever an IP is rejected? Which OID should someone use along with the following command "configure snmpv3 add mib-view "defaultNotifyView" subtree type included [/code]"

    Thank you for your time.

    Best Regards
    George
